Saturn’s moon Titan is one of the most wonderfully weird worlds in our Solar System. In the way that Earth has a water cycle of rain and evaporation, frigid Titan has a methane cycle and lakes of the liquid stuff. Unfortunately, its atmosphere is thick with smudgy clouds and organic haze, limiting our view.
But while visible light can’t penetrate the atmosphere, other wavelengths have better luck. When the Cassini probe was still hanging out in the Saturnian neighborhood, radar and infrared instruments were used to scan the surface. In a new study published this week, a team led by Rosaly Lopes compiled that data to make a geologic map spanning Titan’s surface.
After analyzing the data, the team decided to group the terrain into six types of landscapes: craters, lakes, plains, dunes, hummocky (or mountainous) areas, and something they termed “labyrinth terrains.”
